Looking for Half a Branch to Perch On

The world is divided into six realms. Above the six realms are gods, and above the three realms are immortals. In the three realms, humans, demons, spirits, and immortal cultivators coexist. There is a way in the six realms, and each of them follows it. However, some people follow the Tao, and some people do the opposite. Those who do the opposite will break the order, get trapped in obsessions, and start a bloody storm from now on. Things change, but the past must have an ending. ---------------------------------- "I don't know how long I waited. She has been gone for a long time. At first, I still remember how many years she left. But then, I thought, time is not important anymore. She will always come back. When she is gone, I will take care of the world for her." "How are you sure she will come back?" "Because I won't let her get lost, I will protect her forever."
